SPECIFICATION forming part of Letters Patent No. 510,136, dated December5, 1893. Application tiled September 4,1893- Serial No. 484,698. l (Nomodel.)

To all whom it may'concern:

Be it known that I, THOMAS HIPWELL, of Long Island City, Astoria, in thecounty of Queens and State of New York,have invented an Improvement inGas-Stoves, of which the following is a specification.

This stove is especially adapted to the heating of apartments, theobject being to provide a large extent of metallic heating sur- Io facefor giving heat tothe atmosphere ofthe room, and at the same timepreventing the objectionable odors arisingfrom partially consumedhydro-carbon vapors. In instances where gas has been made use of forheating purposes, there is considerable risk of the lower part of thestove becoming too highly heated, and also of imperfect combustion ofthe gas jets. My present improvement is intended to obviate thesedifficulties and con zo sists of the combination of devices herein 2 forthe heating drum D, which drum is pref# erably of sheet metal withsuitable openings 3 5 that are of an ornamental character and mica 1sintroduced at 3, within the Ydrum and to close the openings at the lowerpart ofthe drum so as to prevent air passing in at this part of the drumand to cause the said drum t0 act as a chimney for the gas burner. Thedrum is removable from the holder 2, and by preference it is providedwith lugs 13 for passing through mortises at one side of the holder andwith an indentation or depression at the other side of the holderadapted to receive a spring latch 5. The socket E, is supported by armsthat project out from it and pass into mortises in the sheet metal ofthe oase below the air distributer, and one of these arms is tubular,and the gas pipe and cock E are connected to the end ofA this tubulararm outside the sheet metal case B, and usually provision is made forconnecting with the gas pipe outside the cock a flexible pipe for thesupply of gas, and this socket E, is screw threaded on its inner surfaceto receive the bottom of the sheet metal burner Il, which burner ishollow, and the lower part 6, is conoidal and the upper part 7, forms areflector. In thel nearly vertical edge of the burner there are holes at8, through which the gas issues and forms nearly horizontal jets, and Iprovide an equalizing plate I, preferably of perforated sheet metal, andresting at its edge upon the air distributor near the outer ends of theopenings in said air distributer, and the inner part of the equalizingplate has a hole through which the lower end of the burner passes as itis screwed into the socket E. It will now be apparent that when the gasis turned on and the jets ignited, the flames extend out nearlyhorizontally and are closely adjacent to the interiorl of the heatingdrum, andthe atmosphere as it passes upwardly to the flame is directedoutwardly by the conical under surface of the sheet metal burner H, andthe volume of airis arnple for a perfect combustion of the gas, and theheated products of combustion pass up closely adjacent to the interiorsurface of the heating drum, and in addition to this, the upper surface7 of the sheet metal burner becomes a reflector for throwing the heatrays from the fiames from one side of `the burner across to the interiorsurface of the heating drum at the other side of therburner, thusdirecting the heat rays and causing them to concentrate upon the sheetmetal of the heating drum, and insuring the transmission of heat fromthe burner to the heating drum and to the atmosphere surrounding saidheating drum; and in addition to this the heated products of combustionpass up through the drum and escape through the perforations in theupper part of such drum, and the gas jets admitted intorthe sheet metalburner become heated by contact with the under side of the reflector 7,and the distance between the holes S, and the socket E, is su'icient toprevent much heat being conducted down by the coni- IOO cal portion 6,of the burner to said socket E- I-Ience the lower part of the stove iskept at a lower temperature, and the risk of injury to a floor orcarpet, either by conducted or reflected heat, is entirely prevented.

I claim as my inventionl. A burner for a gas stove composed of sheetmetal with a conoidal lower portion 6, and an upper reflecting portion7, there being holes for the jets around the burner and 1n the nearlyvertical edge thereof, so that the jets of llame pass out nearlyhorizontally, substantially as setforth.

2. A burner for a gas stove composed of sheet metal, with a conoidallower portion 6, and an upper reflecting portion 7, there being holesfor the jets around the burner and 1n the nearly vertical edge thereof,so that the jets of flame pass out nearly horizontally, in combinationwith the socket E, into which the burner is screwed and the gas pipeformed by one of the arms of the socket, a base supporting the arms,sockets and burner, an air distributer, a heating drum resting upon theupper edge of the air distributor, and connected therewith, such airdistributer and drum being of sheet metal having openings therein,substantially as set forth.

3. A burner for a gas stove composed of sheet metal, with a conoidallower portion 6, and an upper reflecting portion 7, there being holesfor the jets around the burner and in the nearly vertical edge thereof,so that the jets of flame pass out nearly horizontally, in combinationwith the socket E, into which the burner is screwed and the gas pipeformed by one ot' the arms of the socket, a base supporting the arms,sockets and burner, an air distributer, a heating drum resting upon theupper edge of the air distributer, and oonnected therewith, such airdistributer and drum being of sheet metal having openings therein, andthe perforated equalizing plate above the air distributer and extendingto the base of the burner, substantially as set forth.

Signed by me this th day of August, 1893.
